An in-depth look at the land of Oz, incorporating TONS of detail -- I honestly didn't realize the books went into this much depth on Oz. The system is built to support the setting, with assumptions like "bonds of friendship are crucial" and "death is unknown." The game rules are very simple, but this fits the property -- you don't want to be looking up detailed grappling rules when the only real question is whether you can escape to the forest. (One exception is the magic rules, which are considerably more complex. I'm not faulting them, however, as magic is a VERY complicated subject, and you can't handwave the rules it if the PCs will be using it.) The included adventure (almost more of a mini-campaign!) is long, detailed, and looks enjoyable. I'm impressed with this book.
